5.4.1 Overview of disaster recovery

Disaster recovery refers to measures that are taken for unexpected events such as system shutdown caused by a large-scale disaster.

JP1/AJS3 supports disaster recovery that copies JP1/AJS3 data on the shared disk to a shared disk at a remote site. If the system fails because of an event such as a disaster, the JP1/AJS3 system at the remote site can continue operation by using the copied data. The disk copy and mirroring functionality of the hardware is used to copy data between shared disks.

The following figure shows the concept of disaster recovery supported by JP1/AJS3.
